A) \[C{{u}^{+}}\]
B) \[C{{u}^{2+}}\]
C) \[N{{i}^{2+}}\]
D) \[Ni\]
Correct Answer: A
Solution :
Electronic configuration of \[_{28}Ni=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{8}},4{{s}^{2}}\] \[N{{i}^{2+}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{8}},4{{s}^{0}}\] \[_{29}Cu=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{s}^{8}},4{{s}^{0}}\] \[C{{u}^{+}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{10}},4{{s}^{0}}\] So, the given configuration is of \[C{{u}^{+}}\]You need to login to perform this action.
